To find the answer u are looking for we must first come up with out eqaution.

lets use the equation (3.14) (2^2) = 30. first we must do the 2 squared which gives us 4 resulting in (3.14) 4=30 now we multiply pi with 4 resulting in 12.56=30 now we do the division ... and my answer is 2.39 i am not sure if this is right though so take caution when using my response

I believe the answer is 12.56 due to the fact that you would use the formula v=3.14 x 2^2
